Description

The present invention relates to a display device for displaying a stock status of articles stored and stored in a refrigerator or the like.

(B) Conventional technology Conventionally, a display device that manages the stock status of articles stored in a refrigerator or the like and notifies the user when a predetermined storage period determined for each article has elapsed. For example, Japanese Utility Model Laid-Open No. 63-137280 and
There is a publication No. 0183.

In the above publication, a setting unit that also serves as a display unit of a plurality of stored items, and sets a predetermined storage period of each of the stored items, and a predetermined unit in which the storage period of each of the stored items measured by the timer unit is set. There is disclosed a storage period notifying device provided with one notifying unit for notifying that the storage period has elapsed according to each of the stored items.

On the other hand, the above publication discloses a management device that displays the number of remaining storage days for each article from the entry date and the exit date when the check key is operated, and the number of remaining storage days has become a predetermined value or less. In this case, a technique is disclosed in which the article is stored, and each time the door is opened, it is notified that the number of remaining storage days has become equal to or less than a predetermined value.

(C) Problems to be Solved by the Invention In the above-mentioned publication, there is no means for confirming the storage period of the stored item, and the notification is made only after a predetermined storage period has elapsed. Lack of storage period confirmation function for management. In addition, since there is no means for distinguishing and displaying the display state by the operation at the time of storage of the storage and the display state by the operation at the time of storage, the storage operation is not distinguished. If a user accidentally presses a switch for a retrieval operation to perform the above operation, the user cannot be aware of the switch, and there is a fragility that information already input is accidentally deleted.

On the other hand, in the above-mentioned publication, when a predetermined number of days of stock elapses for each article when the check key is operated, a notification for taking out the article is performed each time the door is opened. However, when entering goods at the time of entry / exit, it is necessary to enter the number of articles, and when entering multiple types of articles, the input operation becomes particularly complicated, making it difficult to perform the input operation easily. there were.

In view of the above, the present invention provides an inventory management device in which display modes are clearly distinguished and input operations for each mode are reduced.

(D) Means for Solving the Problems The inventory management device of the present invention includes a display panel on which a plurality of types of articles and display modes are displayed, and a plurality of article designation keys provided corresponding to each display on the display panel. And a two-color coloring diode, a counter for counting the date and time, a mode designation key for designating one of a plurality of display modes such as an input mode, an erasing mode, and a stock confirmation mode, and a display unit for displaying the number of days for storing the articles. And a control device that controls the operation state of the corresponding diode and the display state of the display unit based on the operation of each designation key, and the control device sets each diode to a different light emission state for each designation mode. It is.

In addition, in order to clarify the correspondence between the designated article and the number of storage days in the inventory confirmation mode, the control device, after the inventory confirmation mode is designated by the mode designation key, when the article designation key is operated, The light emitting diode corresponding to the designated article may be changed to a different light emission color, and control may be performed so as to display the number of storage days from the storage date.

Further, in order to prompt the removal of the article, the control device includes:
It is preferable to provide a storage unit for storing a predetermined proper storage period for each article, and to control to turn on a light emitting diode corresponding to the designated article when the number of storage days from the date of entry exceeds the proper storage period.

(E) Function Generally, a two-color light emitting diode stores red and green LEDs, each having a light emitting portion, in a single container, and changes the voltage applied to each LED to change the color of the entire container. An element whose state can be changed from red to green. By using the characteristics of this element, the applied voltage is varied so that the color development state for each display mode corresponding to the mode designation key is different. By doing so, there is a one-to-one correspondence between the display mode and the coloring state of the LED. For this reason, the number of mode designation keys and lighting devices can be reduced.

Also, when the inventory confirmation mode is specified and the item designation key is operated, the light emitting diode corresponding to the key changes to a different color and the number of days for storage is displayed, so that the specified item and the number of days for storage are clear. Is displayed, and it becomes easy to distinguish particularly when there are a plurality of input articles.

Further, when the storage period exceeds the proper storage period, the diode corresponding to the article is automatically turned on, and this lighting state can be used as an alarm display. If it is lit in red, the alarm display effect is further increased.
